How can we improve Excel for Windows (Desktop Application)?

Don't change the links to previous steps of same Query in Power Query

Please don't change the links to previous steps of Query (let's say step 5 uses a variable set up in step2), if a user adds a step 3. Now PQ changed link in step 5 to step 3. Now, due to that, it's just impossible to use such links (they may be changed unintentionally).
